ok. I got another one:
Took some time to figure out the "auto-engage" of wah-wahs, but I got it now :-)
Set up everything, works fine, wah engages when the pedal is moved, so far - so good.
Patch has been saved.
I select the wah-block and dial in another wah with the joystick, the "bypass assign" resets to "EXP toe switch".
I got to re-assign to EXP1 in the "menu / bypass assign screen" and save it again, before it works as set up before.
Otherwise the controller will show the movement from 0-100%, but no fx.
It´s quite annoying, because you have to re-assign and save the preset after every singke change to get it work properly.
Turning back to the saved wah-block (so to say, the preset as it has been saved) will let the bypass assign set to "exp toe switch",
it´ll not return to the saved setting.
Maybe this has been posted before?!
